Parody of Amazing Spider-Man #39. This issue is famous for revealing the identity of the Green Goblin and also for being John Romita's first issue of the series. Personally, though, I am always reminded of a Marvel back-of-the-issue subscription ad that also used a parody of the original cover. I think it had a Christmas theme, the Goblin had a Santa hat and Peter was wrapped in holly. I could be wrong. This is the solicitation image; in the final cover, the Goblin has a fork in his hand.
